The SSC board exam is exactly one month from today. That means students have less than 30 days for preparation. These remaining days are very crucial for them. How to utilize the time, what should be done, what should not be done, what are important points to be considered. What are parents and teachers supposed to do?

Blue-black patch appear on a bruised skin.

When there is bruising, the delicate capillaries present in the skin are ruptured. The blood is clotted internally and forms the bluish-black patch. It is the protective arrangement done by the body so that there is no internal bleeding or blood loss.

When there is a cut on your finger, does it keep on bleeding? Why?

As soon as there is a cut on the finger, it starts bleeding. But after some time (about 2-3 minutes) the bleeding stops. This is because at the site of bleeding clotting reactions take place. The blood cells known as blood platelets help in plugging the leak in the capillary due to which bleeding stops.

We should eat fruits and leafy vegetables.

Fruits and leafy vegetables are a rich source of vitamins and minerals. They help us to keep fit. Leafy vegetables contain minerals such as iron which is essential for forming hemoglobin.

Plants also need minerals.

Plants also need minerals for their healthy growth.

From where do plants get the inorganic material other than carbon dioxide and oxygen?

Plants absorb inorganic materials from the soil. Manure and fertilizers that are added to the soil help the plants to get such essential materials.

Democracy :

The term democracy refers to the rule of people either by themselves (Direct Democracy) or through their elected representatives (Indirect Democracy). Democracy is a way of life that respects the freedom of citizens, protects to the minorities and grants fundamental rights to the people. It is operated by means of tree and fair elections, conducted by an autonomous Election Commission, periodically. It is put into operation by political parties who put up candidates. Every eligible citizen, under the principle of universal adult franchise has right to vote. The government is voted in and voted out at periodical elections. Since it is not feasible to practise direct democracy, it is indirect or representative in modern states.

Parliamentary Democracy :

This form of democracy originated in England; wherein the King / Queen is the titular head and the powers are exercised by the Council of Ministers, headed by the Prime Minister. The leader of the majority party / alliance in the elected house is appointed as the Prime Minister. The Council of Ministers is collectively responsible to the legislature and can be removed by passing a vote of no-confidence. India, too, has adopted parliamentary system.

Presidential democracy :

This system originated in the USA and is based on the principle of separation of powers. The President is the head of the state as well as the government. He is directly elected by the citizens for a specific period. There is no provision for his removal by passing a vote of no-confidence. However, he can be impeached for the violation of the Constitution by the American Congress. France has semi-Presidential system.

An electric current, even if it is very weak, produces a magnetic field. An ion current travelling along the nerve cells in our body produces a magnetic field. This current is very weak; hence, the magnetic field produced is also weak. When we touch an object, the nerves in our body carry an electrical impulse to the muscles to be used. This impulse produces a very weak magnetic field for a short duration. This field is only about 10-9 times the earth’s magnetic field.

Of various body organs, a comparatively significant magnetic field is produced in heart and brain. Magnetic Resonance Imaging (MRI) is a technique used to obtain the images of different parts of the body (including the heart and brain), using the production of magnetic field in the body. Analysis of these images is useful in medical diagnosis.
